胺对镍系催化了二烯聚合规律的影响

以二乙胺为例研究了胺对Ｎｉ（ｎａｐｈ）２－Ａｌ（－Ｂｕ）３－ＢＦ３·ＯＥｔ２＋ｎ—Ｃ８Ｈ１７ＯＨ（简称Ｎｉ－Ａｌ－Ｂ＋ＲＯＨ）和Ｎｉ（ｎａｐｈ）２－Ａｌ（ｉ－Ｂｕ）３－ＢＦ３·ＯＥｔ２＋ＣＨ３ＣＯＯＣ４Ｈ９（简称Ｎｉ—Ａｌ—Ｂ＋ＢＡ）两体系聚合活性和聚合物分子量的影响，并与Ｎｉ—Ａｌ—Ｂ体系进行了对比．考察了通常条件下肢的允许含量，讨论了有胺存在时Ｎｉ／Ｂｄ、Ａｌ／Ｎｉ、Ａｌ／Ｂ摩尔比的变化对聚合规律的影响。结果表明：胺的含量高于２０ｐｐｍ时将使聚合活性和分子量降低，提高催化剂用量可以抑制胺的不利影响。     

基于容差关系的不完备信息系统的属性约简

粗糙集理论是一种处理不确定性知识的有效工具,属性约简是其核心内容之一,然而对于属性值有缺省的不完备信息系统,基于等价关系的经典粗糙集理论已经不再适用。由于容差关系下的不完备信息系统的属性约简的定义与经典粗糙集的属性约简定义相似,可以用容差关系对粗糙集理论进行扩充。文中通过定义容差关系下的可辨识矩阵,运用可辨识方法,得到了一种属性约简算法;接着分析了算法的不足之处,并且在此基础上提出了增加约简效率的改进型算法;最后通过一个数值例子,说明了该算法是合理的和有效的。

Rapid pyrolysis of brown coal and oil shale

A brown coal, peat and oil shale were subjected to a rapid pyrolysis process and medium-heat-value gases together with tar were collected. The char residue was of high activity and suitable for gasification to create a two-stage gasification system. The coal-tar is used for manufacturing liquid fuels and chemicals.     

Integrated UV-based photo microreactor-distillation technology toward process intensification of continuous ultra-high-purity electronic-grade silicon tetrachloride manufacture

Ultra-high-purity silicon tetrachloride (SiCl₄) is demanded as an electronic-grade chemical to meet the stringent requirements of the rapidly developing semiconductor industry. The high requirement for ultra-high-purity SiCl₄ has created the need for a high-efficient process for reducing energy consumption as well as satisfying product quality. In this paper, a mass of production technology of ultra-high-purity SiCl₄ was successfully developed through chlorination reaction in the ultraviolet (UV)-based photo microreactor coupled with the distillation process. The influences of key operational parameters, including temperature, pressure, UV wavelength and light intensity on the product quality, especially for hydrogen-containing impurities, were quantified by the infrared transmittance of Fourier transform infrared spectroscopy (FT-IR) at 2185 cm^-1 and 2160 cm^-1 indicating that characteristic vibrational modes of Si—H bonds, as well as the operating conditions of distillation were also investigated as key factors for metal impurities removing. The advanced intensification of SiCl₄ manufactured by the integration of photo microreactor and distillation achieves the products with superior specifications higher than the standard commercial products.
